Patriota says that the latest news on Chavez indicates "stabilization and even positive developments."

Chavez underwent his fourth cancer-related surgery in Cuba last week. He's remained secretive about the exact nature of the cancer that he's been battling for more than 18 months.

The Brazilian official offered no more details regarding Chavez's health. He said he's staying informed through conversations with Venezuela's Vice President Nicolas Maduro and Brazilian diplomats in Venezuela.
